LOOSE-LEAF BINDER.

Application filed August 25, 1924. Serial No. 733,998.

My invention relates to loose-leaf binders, its object being to providea binder simple in construction and of operation.

The said invention consists of means hereinafter fully described andparticularly set forth in the claim.

In the annexed drawing:

Figure l represents, in perspective, a loose-leaf binder embodying myinvention, t-he cover being shown open.

Fig. 2 represents, upon an enlarged scale, a transverse section.

Fig. 3 represents, on said enlarged scale, an end elevation.

The illustrated embodiment of my invention includes a rectangular coverconsisting of a stiff bottom cover-member l, a stiff top cover-member 2,and a back member 3 to which the two members 1 and 2 are hinged ortiexibly connected.

At equal distances from the ends of bottom-member l, are secured one end4 of each of two coiled springs 5, by means of suitable fasteners suchas rivets 6. These springs are coiled around the straight body portionof a rod T Whose t-Wo ends are each formed With a hook-shaped member 8,each of Whose planes are angularly related to the axis of the bodyportion of the rod, preferably right-angularly. Said axis lies parallelwith t-he edges of the cover.

The other ends 9 of said springs are secured, as shown, to the baseportion of said member 8, respectively.

The outer ends of said member 8 are free, as shown.

The springs therefore act as pivots for the rod and members 8 and tendto hold same in their closed position as shown in full lines in Fig. 2.

Then it is desired to secure a set of loose leaves, one of the hooks 8is grasped and raised to assume the position shown in dotted line inFig. 2, whereupon the set of lea-ves l0 is placed in position, and thehook released. The free ends of said hooks Will thereupon impinge uponthe uppermost leaf and hold the entire set securely in place. The outeror free ends of the hooks are preferably made blunt, as shown, so as notto injure the surface of the uppermost leaf. To remove a sheet orsheets, the reverse of the above operation is affected.

What I claim is:

A loose-leaf binder comprising the combination with a suitable cover; ofa sheetfastener consisting of a rod resting upon the inside of the coverand bent at its tvvo ends to form two hook-shaped members Whose planesare substantially at right angles to the axis of the rod, and tWosprings coiled about the said rod and respectively adjacent to saidhook-shaped members, one end of each such spring secured to said coverand the other end to the adjacent hookshaped member, the axis of saidrod being parallel with the said cover, said springs alone serving as apivotal connection of the rod With the cover and as a resilient means topress the hooks into closed position.

Signed by me this 30th day of July, 1924.
